Back in December, our 1993 4020 Fadal went belly up and I started getting C axis overload errors on the control upon startup and the Baldor vector drive was throwing a DC Bus HIGH on the inverter. I went through the routine and checked all my fuses, tested the regen resistors for resistance, etc. Regen resistors read 7ohms in parallel. I came to the conclusion that my inverter had failed and ordered a new Glentek inverter. Upon install, spindle turns on and runs but when you hit M5, spindle coasts to a stop and I am getting a DC bus high code on the inverter and an inverter Fault Error on the control. I'm stumped on this one. Any idea's would be much appreciated.

Thanks
